Apple - Terminal opens new tab instead of new window with Command-N

Yes, and this was very frustrating when I noticed it since I only ever use tabs in a browser, not to mention opening the tab bar resizes the window >:O

Go into System Preferences -> Dock, then make sure that "Prefer tabs when opening documents" is NOT set to "Always".

You can press Option-Command-N to open a window even if you set always open documents in tab in Dock preferences (this is handy).
